摘要 ：根据国内外相关设计标准和规范，讨论了恒温恒湿类和对湿度有高限控制要求的空调系统采用的空气处理和自动控制方式。在这类空调工程设计中，应该对其能耗和节能问题给予特别的重视，提倡弃用二次加热(再热)，以降低能耗。 关键词 ：空气处理,相对湿度控制,二次加热,节能 Discussion on energy saving design of air conditioning engineering with constant temperature and humidity and high limit control of humidity By Zhou Zuyi★ Abstract ：Based on the correlative engineering design standards and regulations at home and abroad, discusses the air handling and automatic control mode ought to be used for air conditioning systems with constant temperature and humidity and high limit control of humidity. Due stress should be paid to energy consumption and energy saving during design of these projects. Recommends not applying reheat for reducing energy consumption.
